Optical imaging lens assembly

An optical imaging lens assembly, sequentially from an object side to an image side of the optical imaging lens assembly along an optical axis, comprising:

• a first lens having negative refractive power;
• a first prism having an incident surface, a reflecting surface, and an exit surface, and an angle between the reflecting surface of the first prism and the optical axis being 45°;
• a stop;
• a second lens having positive refractive power;
• a third lens having refractive power;
• a fourth lens having positive refractive power;
• a fifth lens having negative refractive power;
• and
• a second prism having an incident surface, a reflecting surface, and an exit surface, and an angle between the reflecting surface of the second prism and the optical axis being 45°,
• wherein 2.50<(R1−R2)/(R1+R2)<4.00,
• R1 is a radius of curvature of an object-side surface of the first lens,
• R2 is a radius of curvature of an image-side surface of the first lens,
• 7.00<f345/R10<12.00, and
• f345 is a combined focal length of the third lens, the fourth lens, and the fifth lens, and R10 is a radius of curvature of an image-side surface of the fifth lens.
